✅

Use context_processor, do as below and you should be able to access os.environ['DJANGO_SETTINGS_MODULE'] as SETTING_TYPE in templates. Example you can use {% if SETTING_TYPE == "settings.staging" %}

project/context_processors.py

import os 

def export_vars(request):
    data = {}
    data['SETTING_TYPE'] = os.environ['DJANGO_SETTINGS_MODULE']
    return data

project/settings.py (your actual settings file)

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                 ...
                  'project.context_processors.export_vars',
                 ...
            ]
         }
      }
   ]

Extending on @vinay kumar‘s comment, you can create a custom template filter in the following way:

application/template_tags_folder/template_tags_file.py

from django.template.defaulttags import register
import os

@register.filter
def env(key):
    return os.environ.get(key, None)

And then in your template you can access it this way:

template.html

{% if 'DJANGO_SETTINGS_MODULE'|env == 'app_name.staging_settings' %}

Finally I leave a django docs reference and a stackoverflow reference for creating custom template tags and filters in django.
